Thickening Agents (Cosmetic Ingredients)

Thickeners are used to adjust the viscosity of cosmetic products. This helps improve the texture and feel during use, while also contributing to product stability. In water-based formulations, water-soluble polymers are commonly used as thickeners, whereas oil-based formulations often utilize polymer esters.

Since these polymers significantly affect the sensory experience during application, various thickeners are selected according to the specific purpose of use.
